9.1.7 Checkerboard V2 Codehs -

Inside the nested loop, use the (row + col) % 2 logic to assign 1 to the correct positions using the syntax grid[row][col] = 1 .

The core of this challenge lies in understanding how to access specific elements in a list of lists and applying a mathematical condition to alternate values. The Core Logic: The Modulo Operator 9.1.7 Checkerboard V2 Codehs

To solve the exercise, you need to create an 8x8 grid (a 2D list) and fill it with alternating 0s and 1s to form a checkerboard pattern. Inside the nested loop, use the (row +

The autograder often checks if you actually changed the values in the list using my_grid[row][col] = 1 . Simply printing a pattern without updating the list will likely cause the test to fail. The autograder often checks if you actually changed

To create a checkerboard, we use the row and column indices. If the sum of the and column index is even, we assign one value (e.g., 0); if it is odd, we assign the other (e.g., 1). This is easily checked using the modulo operator ( % ): if (row + col) % 2 == 0: (Sum is even) else: (Sum is odd) Step-by-Step Implementation
